Parasitic protozoan, TEM

Parasitic protozoan. Coloured transmission electron micrograph (TEM) of a trypanosome protozoan (Trypanosoma sp.). The nucleus (centre), cell membrane (outline, pink) and flagellae (upper left and bottom centre) are seen. Trypanosomes undergo part of their development in the blood of a vertebrate host. Two species, which are transmitted through the bites of tsetse flies, cause sleeping sickness (African trypanosomiasis). Another species, which is transmitted by reduviid insects, causes Chagas disease. Both diseases may be fatal if not treated. Magnification unknown

TEM E.Coli

False colour transmission electron micrograph of the bacterium Escherichia coli, a normal member of human intestinal flora. Under certain conditions it becomes harmful, causing infection in the intestinal or urinogenital tracts. The micrograph shows the bacterium dividing into 2 daughter cells by the process of binary fission. The red areas highlight the nucleic acid or DNA, which carries the genetic information. The DNA lies in the bacterial cytoplasm & is not bound by a separate membrane. As experimental laboratory organisms, E. coli bacteria have played a major role in the development of genetic engineering. Mag: x26, 775 at 10cm tall. Microcosmos P.96 fig.5.16
